Endring i spekktjukkelse og kroppsvekt under dietida og deres påvirkning av kullstørrelse hos TN70 purka i påfølgende paritet
Austlid, Hilda (Master thesis, 2022)Dagens TN70 purke har blitt avlet frem for svært god fruktbarhet med store kull og gode moregenskaper. Store kull som krever mye melk under dietida vil kunne gi store endringer i spekktjukkelse og kroppsvekt hos purkene. ... -
Genetic analyses of heart- and lung volume and correlations to mortality in pigs
Prestrud, Nina Kristin (Master thesis, 2021)The occurrence of sudden cardiac death in pigs (Sus scrofa domestica) is a known problem. Sudden death of pigs causes economic consequences for the farmers and is a challenge for animal welfare. Compared to the wild boar, ... -
Genetic analysis of lifespan in Irish wolfhounds
van Gemert, Chantal Johanna Anna Hermina (Master thesis, 2021)Irish Wolfhounds are an ancient and large dog breed. Their lifespan is an average of 7 years only, which is associated with their size. The genetics behind the short lifespan and the combination with different known diseases ... -
Genetic characterization of a small closed island population of Norwegian coastal goat
Berg, Peer; Groeneveld, Linn Fenne; Brekke, Cathrine; Våge, Dag Inge; Sørheim, Kristin; Grøva, Lise (Peer reviewed; Journal article, 2020)The Norwegian coastal goat is a national and endangered breed. Coastal goat populations are mainly divided with a large mainland and two small island populations. The objective of this study is to describe genetic diversity ... -
Genetic variation in recombination rates and genetic shuffling in pigs, cattle and Atlantic salmon
Brekke, Cathrine (PhD Thesis;2022:17, Doctoral thesis, 2022)Meiotic recombination ensures proper segregation of homologues chromosomes in meiosis while also breaking down linkage disequilibrium and creating novel haplotypes by shuffling alleles of genes located on the same chromosome. ... -
Genetic variation in relation to stress from computed tomography in Norsvin Landrace pigs
Heggli, Andrew (Master thesis, 2019)Resilience towards stress is an important trait as it has implications for animal welfare, and can reduce labour costs. Though some traits included in breeding programs cover disease resilience, general resilience towards ... -
Genetisk analyse av egenskaper fra eksteriørbedømmelse av islandshest på unghestskue og senere utstillinger
Fredenlund, Karianne (Master thesis, 2022)Denne oppgaven ble formulert etter et ønske fra Norsk Islandshestforening. Hovedmålet med studien var å undersøke om noen av hestene som møtte på unghestskue i 2009 – 2011 hadde blitt stilt ut flere ganger, og om det var ... -
Impact of method choice on inbreeding coefficient estimation : a study of inbreeding in five beef cattle breeds in Norway
Wedaa, Malin Olsen (Master thesis, 2023)In 2020 was genotyping implemented into the populations of Norwegian beef cattle breeds of Hereford, Charolais, Aberdeen Angus, Limousin and Simmental. This development provides an opportunity to estimate genomic inbreeding ... -
Improved dairy cattle mating plans at herd level using genomic information
Bérodier, Marie; Berg, Peer; Meuwissen, Theodorus; Boichard, Didier; Brochard, Mickaël; Ducrocq, Vincent (Peer reviewed; Journal article, 2021) -
Inbreeding Trends in Norwegian Cattle Breeds at Risk
Holene, Anna Caroline; Berg, Peer; Sæther, Nina Alvilde Hovden (NIBIO Rapport, Research report, 2021)The Norwegian Genetic Resource Centre estimated the inbreeding rate and thereby the effective population size for all of Norway’s cattle breeds at risk, using the method by Gutierrez et al 2008. When the conservation efforts ... -
Optimized grouping to increase accuracy of prediction of breeding values based on group records in genomic selection breeding programs
Chu, Thinh Tuan; Bastiaansen, J.W.M.; Berg, Peer; Komen, Hans (Peer reviewed; Journal article, 2019) -
Optimum contribution selection (OCS) analyses prompted successful conservation actions for Faroese horse population
Kettunen, Anne Helena; Joensen, Signa Kallsoy; Berg, Peer (Journal article, 2022)The Faroese horse, an endangered indigenous horse breed, is a part of the cultural and societal heritage of the Faroe Islands. Population history describes a severe bottleneck, prompting for quantification of the genetic ... -
